Overview
The Craftsman CMCN621PLB is a cordless nailer running on the brand's 20 volt battery platform. It weighs 10.75 pounds and is sold as a bare tool, since the listing marks battery as not included.
Craftsman's V20 lineup covers a range of nailers and other cordless tools sharing one battery system, and the bare tool spec means buyers who do not already own a compatible 20 volt battery and charger will need to add one separately.

- 10.75 pound weight
- Bare tool, battery not included
- 4.6 star rating from 151 reviews
Who it's for
Fits someone already invested in Craftsman's 20 volt battery system who wants to add a cordless nailer without buying another battery and charger. Not a complete kit for a first-time cordless tool buyer, since power is sold separately.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cordless, no compressor or air hose needed
- Shares batteries with Craftsman's 20 volt line
- Rated 4.6 stars across 151 reviews
- Light at 10.75 pounds for overhead work
- Sold bare, battery and charger not included
Performance notes
Running on the 20 volt platform means driving force comes from a rechargeable pack rather than a compressor and hose, trading outright power for the freedom to move around a job without an air line. At 10.75 pounds it is light enough for one-handed overhead work for short stretches.
